Hi! This is David Jackel on behalf of Expert Village and I'm here to talk to you about
what causes a cold. There are many, many viruses that cause the symptoms that we call the common
cold, which is why it's so hard to fight the cold. Because there are so many different
viruses, it's so hard to come up with a vaccine. So what causes us to catch this virus? Two
things; weaken immune system and exposure to the germs. Your immune system can be compromised
by various factors, including stress when you're so worked up that your body can't performance
normal functions. Having a lack of exercise, having a poor diet, which is why these are
so important and also allergic diseases. To actually catch a cold virus though, you have
to be exposed to it, which means it's going to happen through close contact with other
people who might have the virus, it's going to happen through not very sanitary conditions
where you are touching things that have germs on them, stuff like that. So the two major
factors that are going to cause you to have a cold; are having a weak immune system and
then with that weak immune system, being exposed to germs. So in order to prevent a cold, what
you have to do is boast your immune system and reduce your exposure to germs.
